Summary
Completed in 1978, this Earth-type dam stands at a height of 35 feet and serves primarily for flood risk reduction. With a storage capacity of 150 acre-feet, it covers a surface area of 8 acres and is equipped with a controlled spillway and one valve outlet gate.
While the dam is rated as having low hazard potential, it is considered to be at a very high risk, according to the data provided. This indicates a need for careful monitoring and management of the structure to ensure its continued safety and effectiveness in flood control. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in December 2010.
For water resource and climate enthusiasts, Lorton Robert presents an intriguing case study in dam infrastructure and management. Its location along the TR Canadian River, the specifics of its design and purpose, and the risk assessment data all contribute to a fascinating look at the intersection of engineering, environmental concerns, and public safety. As a key player in flood risk reduction in McIntosh County, Oklahoma, Lorton Robert offers valuable insights into the challenges and opportunities of water resource management in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
